Short Answer
Ask: Who performs the work? Who supervises it? What products are being installed? What happens if decking is damaged? What flashing is included? What ventilation is included? What warranty applies? What insurance does the contractor carry? Who handles permits if required? How is cleanup handled? How are changes documented?
Detailed Explanation
Before signing a contract, homeowners should get clear answers to these questions: Who physically performs the work (employees or subcontractors)? Who supervises the project on-site? What specific products are being installed (manufacturer, product line, grade)? What happens if decking is damaged (per-sheet cost, approval process)? What flashing is included vs. reused? What ventilation is included? What warranty applies (manufacturer and workmanship, terms, coverage period)? What insurance does the contractor carry (general liability, workers' comp, verify with certificates)? Who handles permits if required? How is cleanup handled (magnet for nails, dumpster, site protection)? How are change orders and additional work documented and approved? Getting these answers in writing protects both parties.
Why It Matters
Getting clear answers before signing prevents misunderstandings, disputes, and surprise costs during the project.
